PURPOSE OF REVIEW: This review seeks to describe the role of the asialoglycoprotein receptor (ASGR) in modulating non-HDL lipoprotein levels, platelet numbers and atherosclerosis. RECENT FINDINGS: Genetics studies have revealed that ASGR haplodeficiency provides protection from atherosclerosis. The potential interactions of ASGR with LDL receptor may regulate the rate of LDL uptake and as a result may lower plasma non-HDL cholesterol. ASGR clears senescent platelets and induces the expression of hepatic thrombopoietin. Platelet activity promotes plaque formation and atherosclerosis. SUMMARY: ASGR is a multifunctional receptor specializing in clearance of desialylated glycoproteins and platelets. The impact of ASGR on the levels of plasma non-HDL cholesterol makes it a potential therapeutic target for the treatment of hypercholesterolemia and atherosclerosis.
